Carbohydrate polymeric blend microspheres of sodium
alginate and methylcellulose were prepared and characterized
by differential scanning calorimetry, scanning electron
microscopy, and particle size distribution. DSC
thermograms have confirmed the uniform molecular distribution
of the drug molecules in the microspheres.
SEM micrographs exhibited a spherical morphology of
the prepared microspheres. The drug was released in a
controlled manner. The swelling studies of microspheres
